I found a note that suggests you can only backup one Hyper-V client at a time:

"*Backup of virtual machines within Cluster Shared Volumes (CSV) is supported. In
Hyper-V Server 2008 R2, CSV has a limitation that requires serialized backups. In
Hyper-V Server 2012, CSV supports concurrent backups without that limitation.
Consequently, the CSV timeout setting in the NetBackup Hyper-V policy is only
used in Hyper-V Server 2008 R2 deployments"

 

Here is the troubleshooting guide for your situation:
